After the control terminal is connected, the controlled terminal will also be connected. Strong photoelectric isolation and anti-interference ability. Later, it can drive high-power transistors, MOS transistors, and other occasions that require high voltage driving, or directly drive low-power 24V relays to work. If it is a pulse signal, please note that the limit of 817 is below 4KHZ. For control signals greater than 4KHZ, please do not use this module as it will not work properly.
PC817 Parameters:
Driving Port Signal Voltage:3.6-24V
Output Port Voltage Port: 3.6-30V
The jumper cap can be used to determine whether the output terminal is high potential output or low output.
Each channel of PC817 optocoupler isolation board is independent, can control different voltage at then same time.
Package include: 4pcs PC817 4 Channel Optocoupler Isolation Board
Note:
The input port is shared with GND;
The output ports are independent of each other;
It is optocoupler output.V and G will be connected after input valid signa in input port.

This product is a 4-pack DIY modules, which are used in DIY projects for signal isolation.The signal isolation is achieved by using the optocoupler PC817. So there are four PC817 found on the PCB, and then some additional passive components and terminal block connectors.Note that this module actual size is smaller than what it appears or looks like in the product description pictures.I like it works as described and 4 channels are packed on the same PCB. When input signal is high, there is a LED status light turned on as well.However, product just comes in 4 pcs modules individually packed, without any printed material. It maybe challenging the product is removed from the Amazon or seller remove the listing.So, it is always recommended to include some basic printed material for product specifications, pinouts or usage to make the product more "complete", is it too much to ask for?

I used this optocoupler in a security application to remotely activate strobe and horn devices. Since these devices are critical, I needed to prevent any malicious attempt to short-circuit the ends, which could disable all devices connected in parallel. This optocoupler isolates the signals effectively, allowing me to handle any short circuit without damaging the controller board or disrupting the system. Its ability to isolate control and output signals ensures that the system remains operational, even in scenarios where tampering might occur. A practical solution for robust and secure designs.
